Serial No. 289,116.

My invention relates to improvements in the class of safety razors in which a blade is clamped between a guard member and a backing member for shaving. l

An object of my invention is to provide improved means to retain the blade edge in shaving relation to the guard teeth or comb irrespective of the action of the backing mem- -ber,wl1ile permitting the blade to be properly clamped between the' guard and backing members. y

In carrying out my invention I provide a razor having guard and backing members, with movable vmeans carried by one of said members and operative in openings in a .blade between said members to engage edges of said openings tov retain the blade in shaving relation to the guard, said means being movable betweensaid members and adapted to project through thel blade when the latter is placed upon the corresponding member and to engage the other member and be' moved by the latter to permit the members to be clamped upon the blade.

My invention also comprises novel details of improvement more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, inwhich Fig. 1-is a side view of a safety razor embodying my invention, shown assembled for use; l,

Fig. 2 is a side view of Fig. 1;

Fig. 3 is a-plan view with the backing memj ber partly broken;

Fig. 4` is an exploded view, partly in section on line 4, 4, in Fig. 3; I

Fig. 5 is a section on line 5, 5, in Fig. 3;

Fig. 6 is a section on line 6, 6, in Fig. 2;

f Fig. 7 is a detail perspective view, and Fig. 8 is a plan view of the blade.

Similar numerals indicate corresponding parts in the several views.

The numeral 1 indicates a guard member, shown provided with comb-like teeth at 1a, in an ordinary way,- and at 2 isja backing member, between which members a blade 3 is to be clamped. The blade may have one or more cutting edges 3a. The members 1 and 2 may be clamped upon the blade in any desired Way, such as by means of a threaded 1, 'in a well known way. The acking member 2 shown provided with spaced projectlons or pins 8 that are adapted to pass sesy through openings 3fl in the blade and through openings 1c in the guard member, in an ordinary way. In the class of razor described the openings 1c in the guard member permit some lateral movement of the projections 8 and of the blade, so that the user mayhave to make an adjustment'to assure therelquired position of the blade edge relatively to the guard teeth for proper shaving.

In accordance with my invention I pro- `vide movable projections or guides for the blade at 9, which are carried by and project through one of the members, and through the blade, to be engaged b the other member. The projections or gui es 9 are, preferably, resiliently supported. I have shown the projections or guides9 at the ends of springs 10, and the parts 9 and 10 may be formed from springwire, bent at the end portions to form the projections 9, (Figs. 6 and 7). By preference the springs 10 are located in longitudinal grooves 11 formed in the under sides of the guard member 1, and the projections 9 pass throu h holes 12 in guard member 1, (Fig- 7)- member 1, preferably. mid-way of their length, by any suitable means, such as by rivets at 13, (Figs. 6 and 7). In the construction illustrated the projections 9 are arranged he springs 10 may be secured toin pairs near each end of the guard member l,

projections are opposed and spaced apart to permit the passage between said projections 0f the pins 8 when the parts are assembled,

3 and 8).

en the parts are dis-assembled the projections 9 project beyond the surface of the guard membervupon which the blade is to rest, (Figs. 4 and 7). When the blade is placed upon the guard member said projec- 5 tions enter the corner recesses 3b in the blade,

which recesses of each end opening 3 arel spacd substantially the same distance apart as the outer-sides of the projections 9, so that said projections will fit snugly in the recesses of the corres onding opening, (Fi and thereby the lade will be set an retained with its cutting edges in proper shaving position respecting the guard teeth. When the backing member 2 is applied upon the blade said member will engage the projections 9, and as the handle is screwed to the stem 4, to clamp the blade between the guard and the backing members, the projections 9 will be pushed back by the backing member but will 20 remain in the openin 3"'of the blade, thereby retaining the bla e in shaving relation to -the guard teeth at all times when the parts are clam ed together. The-'springs 10 permit the escribed movement ofthe projections 9, (Fig. 6) When the backing member isremoved from the bladefthel vpro'ections 9 will advance through the blade an retain lthe latter upon the guard member, in the position of theparts shown in Fig. 4in consvovenient position to be lifted from the guard .v member. `Whenl the arts are clamped together, (as shown in IFg'), the spring tension of the projections 9 against the backing and 5 to keep from becoming loosene In accordance with my invention the assemblin of the parts is facilitated because the bl e vmay be applied upon the guard member with the projections extending through the blade openings 3, so that the blade will not shift its position upon said member when the backing member is bein applied, and in case the latter member shoul not be accurately placedu n the blade the position of the latter relat1vely`to the ard teeth will not be disturbed.- Any shifting of the backing upon the blade will not alter the osition ofthe lat-ter upon the guard mem l r, and the resiliency of the projections or blade guides 9 does notaect the clam ing of the members 1 and 2 nor the bending of the blade posing curved surfaces of said members.

Changes may-be made in the detailsset forth without departing from the spirit of the appended claims.

Having now described my invention what I claim is:

1. A safety razor com rising detachable guard and backing mem1 ers, the bacln'ng member having pins to pass through openresilient supporting means on the under side vof the adjacent member.

v member tends to cause the threaded (parts 4' ainst the bla e y f tween the opmember to be pressed back by the last named position respecting the guardmemberirrespective of said pins, and means to detachably retain the members clam against the blade, said movable means eing 1n position to en age the opposite member to be pushed back y the latter when said members are clamped a ainst the blade.

' 2. A sa ety razor as slet forth injclaim 1, in which the movable means is carried by 3. A safety razor comprising detachable guard and Fbacking members, the backing member having pins to pass through openings in a blade, spaced projections movably carried by and normally projecting from one of the members and, operative in openings in the blade between said members to1 retain the blade in shaving position respecting the guard member irrespective of said pins, and means to detachably retain the members clamped against the blade, said movable means being inposition to engage the opposite member to be pushed back by the latter when said members arev clamped against the blade. i

4. A safety razor as set forth in claim 3, in which the projections are carried by springs secured t'o the under side of the corresponding member to be moved by the opposing 'member when said members are clamped a ainst the blade.

5. A sa ety razory comprising detachable guard and backinY members, one of said members having sp d holes, guiding projections located and movable in and projecting from said holes to enter openings in a blade between said members, means resiliently supportin said guiding projections upon the correspon 'ng member and away from the 105 blade receiving surface thereof, said projections being in position to enga e the other member to permit said mem rs to bel clamped, and means to clamp said members against the blade.

6. Asafety razor comprising detachable guard and backing members, provided with spaced holes adjacent to opposite ends of one .of the members, springs carried by said member away from its blade receiving surace and provided with idi projections extending through said hoglgs beljnd said surface to enter openings in a blade between said members and 1n posltion to engage the other v member to rmitsaid members to clamp against the lade, and 'means to detachably clamp said members ainst Athe blade.
